Industrial furnaces play an important role in view of the energy consumption.
In this article, possible steps to conserve energy in combustion furnaces are discussed, then several explorative suggestions from the standpoint of furnace design are presented.
In this decade, industrial furnaces have been remarkably improved, however in the trend of recent development of it, heat efficiency has not been always regarded as the first important subject. The writer starts out an analysis of the present furnace situation caused theredy, then discusses available measures which could be taken for energy conservation in furnaces and finally attempts some proposal in regard to the orientation of future developments as it ought to be. As for average means, recovery and reuse of waste heat from furnaces as well as decrease of wall heat loss by better and more carefully designed insulation, are effective.
Subjects which should be considered as matters of greater importance are basic furnace design, consisting of optimum heating rate, furnace profile line and proper furnace selection which meets production line requirements.
This is the time for us furnace engineers to frankly review the above in order to approach better energy conservative furnaces.
Finally, the the themes which should de seriously considered as future tasks are as follows:
Means to reduce energy consumption without affecting product quality or performance. Second, compatibilty of fuel economy and antipollution strategy, and then, an integrated counter-plan for energy saving, which includes not only fuel but every utility and resource such as electricity, water and consumable furnace components.
